GW like Bill I don't think the RES will eat all the FH. I still would go with fewer RES/and or WM as the generally recommended stocking #s are ,in my opinion ,not applicable. Those recommended #s are designed where the stocked fish are being stocked for forage. You are not using the RES/WM as intended by the recommendation thus I would treat them as somewhat akin to a predator and not as a forage stocking.

I think you need a predator in your pond other than RES but it may well work without one.

My thought process. If I wanted large BG as the dominate fish I would not stock them at the high forage recommended #s but at lower rates. Same thing for WM or RES just slightly different #s. I would try to have some adults in at the start to suppress their own offspring through cannibalism and dominance behavior suppression.
